vector(x,y,z)=vector(cos(v)*[3+cos(u)],sin(v)*[3+cos(u)],sin(u))

vector(x,y,z)=vector(8+cos(v)*[3+cos(u)],sin(v)*[3+cos(u)],sin(u))

vector(x,y,z)=vector(-8+cos(v)*[3+cos(u)],sin(v)*[3+cos(u)],sin(u))

vector(x,y,z)=vector(4+cos(v)*[3+cos(u)],0+sin(u),0+sin(v)*[3+cos(u)])

vector(x,y,z)=vector(-4+cos(v)*[3+cos(u)],0+sin(u),0+sin(v)*[3+cos(u)])
